Hey yall i have a 2002 7.3 f250 i have it straight piped, with an 8" lift, on 35's. I just put in a new terminator high pressure pump and procomp ES9000 shocks. I am getting around 9mpg and i cannot figure out why. I know the lift and tires hurt my mpg but it shouldnt hurt it that bad. My rpms dont hang and i can blow a little smoke if i hammer it. I drive my truck super slow and do not accelerate fast. The only thing i can think of is that the injectors could be bad? Please help!!!
